Straßburg
is a town in what used to be the
German
part of Burgundy/Alsace
(the borders of these provinces have shifted over the
years)
but it's now in France.

Delbert von Straßburg is from approximately
1470 when the town was most definitely German!
It didn't become part of France until after
World War I. Don't refer to the town as
Strasbourg
because that's the French spelling.

The funny "ß" character in the middle
of the word is called a "scharfes s" and is
the way that a double - "S" is written in some
places in German words. It's pronounced like an "s",
not like a "B" (which it looks a bit like), or like
"FS" which it also resembles.

It's not even derived from the
Greek
letter "beta" which it looks a lot like (you can
use a beta as a substitute in handwriting if you want) but
is in fact a long "s" (as seen in medieval and
renaissance text) followed by a short "s".

If you don't have one of these in your font set, or on your
typewriter, then it's OK to use a double - "s"
instead. In fact it's even OK to use a single "s"
in this context because spelling rules were pretty slack
in 1470!

The famous German medieval poet
Gottfried von Straßburg
was from this town, and wrote one of the many editions
of the "Tristan and Isolde" romances
appearing in medieval literature.

There's no suggestion that Straßburg has
anything to do with
dance
whatsoever.
